Damn I was planning on a sol-ark package in the spring...
Any recommendations for a non-connected (budget-friendly if possible) brand to look for?
I just installed a sol ark system, and can confirm that they work just as well with a pi and Solar Assistant. Not open source, but integrates well with homeassistant and no need for network connecting the actual electrical equipment, just usb.
I like the MorningStar brand, but they aren't cheap. I wrote a review here if you're interested: http://www.gogreenit.net/index.php?page=morningstar-tristar-60a-mppt
My preference has become Maximum Solar. They work with button and LCD control. It ain't convenient but I reprogram them only twice a year - when transitioning between summer (hot, energy surplus, preserve batteries by not charging them fully) and winter configurations (cold, energy deficit, fill batteries to the maximum). I've thought about automating that, but didn't bother.
Got a link? that name isn't very unique :(
I have a sol-ark and like it though this is concerning. In this case it's dyne on dyne branded and sol-ark has nothing to do with it, as far as we are aware.
If you don't care about the pretty graphs and data points and just want it to do it's job, then getting whatever inverter you want and not connecting to the net solves this problem. Alternatively, locking down traffic to and from this device is something I'll be looking at.
